RESUMO
Subtotal colectomy is often performed on patients with synchronous colorectal cancer. However, compared with colorectal anastomosis, ileorectal anastomosis with subtotal colectomy is more likely to result in bowel dysfunction. The Deloyers procedure is useful in preserving bowel function in a patient with synchronous colorectal cancer. An 87-year-old man presented with bloody stool. Colonoscopy showed masses in the cecum, transverse colon, rectosigmoid, and rectum above the peritoneal reflection. Computed tomography scan revealed no evidence of regional lymph node swelling and distant metastasis. Therefore, robot-assisted low anterior resection, laparoscopic extended left hemicolectomy, laparoscopic cecal resection, and diverting ileostomy were performed. The patient was discharged from the hospital without complications. There was no recurrence, and the patient did not have complaints such as urgency, fecal incontinence, and excretory dysfunction. Hence, minimally invasive coloproctectomy using the Deloyers procedure can be safe and useful in preserving postoperative bowel function in elderly patients.

CLINICAL CASE: The 59-year-old patient complained of hearing loss on the left, ear murmur for a long time, periodic pain and discomfort in the left ear, dizziness for 6 months. She was found to have concurrent vestibular schwannoma in the internal auditory canal and temporal bone paraganglioma. Both tumors were removed in one operation. The schwannoma was removed by translabirinth access due to preoperative deafness, while the glomus tumor was removed during this access. Postoperative biopsy showed the presence of two unrelated diseases: paraganglioma (ICD-0 code 8690/3) and schwannoma (ICD-0 code 9560/0).

We present a combination of distal cholangiocarcinoma of the intrapancreatic common bile duct and intraductal papillary mucinous tumor associated with ductal adenocarcinoma of the pancreatic tail. This clinical case is unique. When analyzing the literature, we found no any case of similar primary multiple malignant tumor. Importantly, final diagnosis of simultaneous malignant pancreatobiliary neoplasia is possible only via intraoperative biopsy after adequate morphological dissection and research of resected organ complex including molecular genetic analysis due to identical histological and immunohistochemical picture of ductal neoplasia.

BACKGROUND: Primary cardiac tumors, while rare, present significant clinical challenges due to their diverse pathology and presentation. Lung cancer frequently metastasizes to the heart; however, cases involving primary cardiac tumors of different origins alongside primary lung cancer are exceedingly rare in the literature. CASE PRESENTATION: We report the case of a 53-year-old female who presented with hemoptysis and was subsequently diagnosed with a left atrial myxoma, pulmonary squamous cell carcinoma, and a thymic cyst. This coexistence of multiple non-homologous tumors in a single patient is exceedingly rare. CONCLUSION: This case underscores the complexity of diagnosing and managing patients with multiple distinct tumors. The simultaneous occurrence of a primary cardiac myxoma, pulmonary squamous cell carcinoma, and thymic cyst is unprecedented, providing valuable insights for future clinical practice.

Objective: At present, the incidence of synchronous multiple primary lung cancer (SMPLC) is increasing, and the treatment is still a challenge. This study aims to investigate the appropriate surgical procedure for treating bilateral primary lung cancer simultaneously. Methods: A retrospective analysis was conducted on clinical data from 32 patients who underwent simultaneous bilateral lung cancer surgery in our team. This data included patient characteristics, pulmonary function indicators, surgical procedures, operation duration, chest tube removal time, postoperative hospital stay, and postoperative complications. Results: Out of the 32 patients, 15 were male, and 17 were female, with an average age of 56.4 ± 8.8 years. The average maximum diameter of the main and minor tumors was 1.8 ± 1.0 cm and 1.0 ± .5 cm, respectively. All surgeries were performed thoracoscopically through intercostal approach. The procedure for the minor tumor was performed first, followed by the main tumor operation after turning over. One case was converted to thoracotomy during the main tumor operation because of bleeding. Postoperative complications occurred in one patient. No instances of respiratory insufficiency or failure were observed after the operation, and there were no perioperative deaths or readmissions within 90 days. Conclusion: Simultaneous bilateral thoracoscopic surgery is deemed a secure and feasible option for eligible patients with bilateral primary lung cancer, and it is advisable to commence the operation on the minor tumor first.

BACKGROUND: The treatment for bilateral synchronous multiple primary lung cancers (MPLC) remains challenging. Simultaneous bilateral video-assisted thoracic surgery (VATS) may be an optimal treatment with curative intent, but its safety and feasibility are controversial. METHODS: One hundred and fifty-eight patients who underwent simultaneous bilateral VATS (simultaneous group) and 79 who underwent two-staged bilateral VATS (two-staged group) were included in this study. Their medical records were retrospectively reviewed and analyzed. RESULTS: The majority of patients were female and non-smokers. The most common surgical plan was lobectomy and contralateral wedge resection in both groups. There was no significant difference in the postoperative complication rate between the simultaneous groups and two-staged group (13.3% vs. 11.4%, p = 0.73). Patients who underwent simultaneous bilateral resection had shorter hospital stays, shorter anesthesia time and less chest drainage compared with those who underwent two-staged resection. Advanced TNM stage, complicated surgical plan and aggressive lymph node resection were risk factors for postoperative complications in simultaneous bilateral VATS. Patients in two groups had similar overall survival and disease free survival (p = 0.2). CONCLUSIONS: Simultaneous bilateral VATS for bilateral lung nodule resection is as safe and feasible as two-staged bilateral VATS. Patients who underwent simultaneous bilateral resection had similar or even better outcomes compared to that of the two-staged group. Simultaneous bilateral VATS is potentially an optimal treatment option for patients with erarly cTNM stage and good physical condition.

BACKGROUND: Surgery is the standard care for patients with early-stage lung cancer, and stereotactic body radiation therapy is an option for those who are medically inoperable or refuse surgery. Medical developments in diagnostic and therapeutic strategies would prolong prognosis of patients with cancer. The number of patients with multiple cancers has also increased. Duplex primary malignant neoplasms are the most common, and triple or more primary malignant neoplasms were extremely rare. This is the first case of sextuple primary malignant neoplasms with lung cancer. CASE PRESENTATION: We report a case of two courses of stereotactic body radiation therapy for an 88-year-old Japanese male patient with six primary cancers in five organs. Cancers were detected in the thyroid, prostate, esophagus, bladder, and lungs. He also had a history of angina pectoris and had undergone percutaneous coronary intervention. Although he was capable of undergoing surgery for lung cancers, he refused it because he had experienced many invasive treatments, such as surgeries and percutaneous coronary intervention. In January 2020, the first stereotactic body radiation therapy was performed for the adenocarcinoma in the right lung. In March 2022, the second stereotactic body radiation therapy was performed for the nodule of the left lung. Although he complained of mild dyspnea after the first stereotactic body radiation therapy, we did not use steroids because his peripheral oxygen saturation was within the normal range. He had pleural effusion, cardiac dilatation, and pericardial effusion 2 months after the second stereotactic body radiation therapy, which improved with the use of compression stockings. CONCLUSION: A total of 43 and 17 months have passed since the first and second stereotactic body radiation therapy, respectively, there is no local recurrence and the patient can walk independently. We safely performed stereotactic body radiation therapy twice for our older patient with metachronous early-stage lung cancers. If another new tumor is detected, stereotactic body radiation therapy would be a good treatment option for the functional preservation of organs.

BACKGROUND: Parathyroid carcinoma (PC) is a rare malignancy, often diagnosed incidentally through postoperative pathological examination. The occurrence of nodular goiter, intrathyroidal parathyroid carcinoma, contralateral parathyroid adenoma (PA), and papillary thyroid microcarcinoma (PTMC) is extremely uncommon, which prompted us to report our case experience. CASE PRESENTATION: We describe a 67-year-old male who presented with a cervical mass causing tracheal compression, which prompted him to seek medical advice. Based on preoperative auxiliary examination results from color Doppler ultrasound, SPECT parathyroid imaging, and blood tests, he was initially diagnosed with a suspected parathyroid adenoma and nodular goiter. Excision of the right lobe and isthmus of the thyroid, and left superior parathyroid gland was conducted, which were sent to intraoperative frozen pathological examination. During intraoperative observation, adhesion around the right thyroid lobe was discovered. Consequently, right central area lymph node dissection was performed due to suspicion of an aggressive malignant tumor. Histology and immunohistochemistry analysis revealed incidental intrathyroidal parathyroid carcinoma, contralateral parathyroid adenoma, classical papillary thyroid microcarcinoma, and nodular goiter. CONCLUSION: Parathyroid carcinoma should be highly suspected when extremely high levels of PTH and severe hypercalcemia are present, which cannot be simply explained by a preoperatively localized parathyroid adenoma, especially when suspicious malignant adhesion is found during intraoperative exploration. In cases where multifocal thyroid nodules are associated with increased uptake of 99Tc-sestamibi, the possibility of coexisting carcinomas should be considered, not only for thyroid malignancy but also for the potential presence of intrathyroidal parathyroid carcinoma.

BACKGROUND: Eosinophilic solid and cystic renal cell carcinoma (ESC-RCC) is a novel subtype of renal cell carcinoma characterized by its relatively low incidence and indolent behavior. We report a rare case of ESC-RCC concurrent with clear cell renal cell carcinoma (ccRCC) in a single kidney. CASE PRESENTATION: A 48-year-old male, was found to have a mixed echogenic mass in the left kidney during a physical examination. He has no history of hematuria and flank pain. An abdominal CT scan revealed a 3.0 * 1.9 * 2.5 cm3 mass with unclearly bordered at the lower pole of the left kidney. Abdominal MRI showed two nodules of different sizes in the left kidney, suggesting the possibility of a tumor. The patient underwent a subtotal nephrectomy, and the postoperative pathological results indicated ESC-RCC combined with ccRCC. The patient recovered well without tumor recurrence during the 12-month follow-up. CONCLUSION: We reported a case of renal composite tumors, comprising the rare ESC-RCC and the more common ccRCC. Imaging combined with postoperative pathological examination is crucial for the definitive diagnosis of these rare tumors.

The mucosa-associated lymphoid tissue (MALT) lymphoma subtype, specifically extranodal marginal zone B-cell lymphoma, is a rare variant. Within this subtype, primary thyroid MALT lymphoma is an uncommon occurrence. The literature provides limited documentation on thyroid MALT lymphomas, as their prevalence is comparatively lower than in other organ sites. The coexistence of papillary thyroid carcinoma (PTC) and thyroid MALT lymphomas is exceedingly rare. It presents a rare case of primary thyroid MALT lymphoma accompanied by PTC, thyroid lymphoma not being considered before surgery. A 64-year-old female patient, who had been experiencing symptoms related to a substantial thyroid tumor for a duration of three years, she refused to do a needle biopsy before surgery and expressed a preference for surgical resection. Consequently, the patient underwent a total thyroidectomy along with lymphadenectomy of the central compartment. A histological examination subsequently confirmed the presence of papillary thyroid carcinoma (PTC) and mucosa-associated lymphoid tissue (MALT) lymphoma. Due to the favorable response of the MALT lymphoma to local treatment and the absence of metastasis in other organs, no further treatment was administered for the MALT lymphoma following the surgery. Currently, the patient exhibits no signs of tumor recurrence based on ultrasound and laboratory evaluations. We also provide an overview of the clinical findings on PTC and MALT lymphoma patients already reported and discuss the possible treatment strategy.

INTRODUCTION: Oncological outcomes in patients with nonclear cell renal cell carcinoma (non-ccRCC) treated with surgery for locoregional nodal disease (ND) remain incompletely characterized. The objective was to investigate the characteristics and outcomes of non-ccRCC patients treated with lymph node dissection (LND) and salvage-LND (S-LND). METHODS: A total of 1627 patients underwent nephrectomy for nonmetastatic non-ccRCC at Memorial Sloan Kettering Cancer Center between 2007 and 2023. Histology was grouped as papillary, chromophobe, unclassified, and rare subtypes. Retrospective evaluation identified 2.5% (n = 40) of patients with nodal disease at time of nephrectomy (synchronous-ND) and 1.1% (n = 18) with metachronous nodal disease limited to the retroperitoneum (metachronous-ND). Patients' demographics and tumor characteristics were recorded and evaluated by univariate and multivariate cox regression models. Recurrence-free survival (RFS) and overall survival (OS) were estimated by the Kaplan-Meier method. Patients who underwent tumor DNA sequencing during their clinical course were considered for genomic analysis. RESULTS: OS trended toward longer in metachronous-ND (51 vs 105 months; P = .2), though 23% of patients with synchronous-ND were recurrence-free at 45 months median follow-up. In multivariate analysis, rare histologies were associated with decreased OS (P = .030) and metachronous-ND with improved OS (P = .036). RFS and OS after S-LND was 15 and 96 months, respectively. Late onset of metachronous-ND/recurrence was associated with improved OS (P = .008). Genetic alterations in SETD2, TP53, B2M, and FGFR3 were exclusively seen in synchronous-ND, and tumor mutation burden (TMB) was also higher in patients with synchronous-ND (P = .016). CONCLUSIONS: Patients with metachronous-ND tend to have prolonged OS compared to synchronous-ND, but a substantial portion of patients with synchronous-ND still enter a durable disease-free state following LND. S-LND can likewise provide long-term survival, particularly in patients with longer time to metachronous nodal recurrence. Synchronous-ND was associated with SETD2, TP53, and NF2 alteration as well as higher TMB.

BACKGROUND: In many Asian hepatocellular carcinoma (HCC) guidelines, resection is an option for multiple HCCs. It is difficult to compare small but multiple tumors vs. fewer large tumors in terms of the traditional tumor burden definition. We aimed to evaluate the role of liver resection for multiple HCCs and determine factors associated with survival benefits. METHODS: We reviewed 160 patients with multiple HCCs who underwent liver resection between July 2003 and December 2018. The risk factors for tumor recurrence were assessed using Cox proportional hazards modeling, and survival was analyzed using the Kaplan-Meier method. RESULTS: In all 160 patients, 133 (83.1%) exceeded the Milan criteria. Total tumor volume (TTV) > 275 cm3 and serum alpha-fetoprotein (AFP) level > 20 ng/mL were associated with disease-free survival. Patients beyond the Milan criteria were grouped into three risk categories: no risk (TTV ≤ 275 cm3 and AFP ≤ 20 ng/mL, n = 39), one risk (either TTV > 275 cm3 or AFP > 20 ng/mL, n = 76), and two risks (TTV > 275 cm3 and AFP > 20 ng/mL, n = 18). No-risk group had comparable disease-free survival (p = 0.269) and overall survival (p = 0.215) to patients who met the Milan criteria. CONCLUSION: Patients with TTV ≤ 275 cm3 and AFP ≤ 20 ng/mL can have good outcomes even exceed the Milan criteria.

INTRODUCTION: Renal cell carcinoma (RCC) is the dominant primary renal malignant neoplasm, encompassing a significant portion of renal tumors. The presence of synchronous yet histologically distinct ipsilateral RCCs, however, is an exceptionally uncommon phenomenon that is rather under-described in the literature regarding etiology, diagnosis, management, and later outcomes during follow-up. CASE PRESENTATION: We aim to present the 9th case of a combination chromophobe RCC (ChRCC) and clear cell RCC (ccRCC) in literature, according to our knowledge, for a 69-year-old North African, Caucasian female patient who, after complaining of loin pain and hematuria, was found to have two right renal masses with preoperative computed tomography (CT) and underwent right radical nephrectomy. Pathological examination later revealed the two renal masses to be of different histologic subtypes. CONCLUSION: The coexistence of dissimilar RCC subtypes can contribute to diverse prognostic implications. Further research should focus on enhancing the complex, yet highly crucial, preoperative detection and pathological examination to differentiate multiple renal lesions. Planning optimal operative techniques (radical or partial nephrectomy), selecting suitable adjuvant regimens, and reporting long-term follow-up outcomes of patients in whom synchronous yet different RCC subtypes were detected are of utmost importance.

Well-differentiated papillary mesothelioma (WDPM) is a rare mesothelial tumor of uncertain malignant potential. We present a unique case of a woman with synchronous WDPM and well-differentiated endometrioid adenocarcinoma (EA) arising from extraovarian endometriosis. A 56-year-old postmenopausal woman presented with a several-month history of right lower quadrant abdominal pain. She had a history of supracervical hysterectomy and bilateral salpingo-oophorectomy secondary to endometriosis. Imaging reported a mass in the right lower quadrant originating from the distal ileum. At laparotomy, the patient underwent a right colectomy with resection of the terminal ileum and excision of a solitary peritoneal nodule. Pathology was consistent with a diagnosis of well-differentiated EA (arising from extraovarian endometriosis) and WDPM. Further treatment consisted of complete surgical staging/debulking and adjuvant chemotherapy directed toward metastatic well-differentiated EA. Surgeons should be familiar with WDPM as a potential finding in women of reproductive age undergoing abdominal surgery for any indication.

BACKGROUND: Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is a rare tumor that few cases have been reported until now. In these cases, either a benign teratoma is malignantly transformed into adenocarcinoma or a collision tumor is formed between a mature cystic teratoma and a mucinous tumor, which is either primarily originated from epithelial-stromal surface of the ovary, or secondary to a primary gastrointestinal tract tumor. The significance of individualizing the two tumors has a remarkable effect on further therapeutic management. CASE PRESENTATION: In this case, a mature cystic teratoma is co-existed with a mucinous cystadenocarcinoma in the same ovary in a 33-year-old Iranian female. Computed Tomography (CT) Scan with additional contrast of the left ovarian mass suggested a teratoma, whereas examination of resected ovarian mass reported an adenocarcinoma with a cystic teratoma. A dermoid cyst with another multi-septate cystic lesion including mucoid material was revealed in the gross examination of the surgical specimen. Histopathological examination revealed a mature cystic teratoma in association with a well-differentiated mucinous cystadenocarcinoma. The latter showed a CK7-/CK20 + immune profile. Due to the lack of clinical, radiological, and biochemical discoveries attributed to a primary lower gastrointestinal tract tumor, the immune profile proposed the chance of adenocarcinomatous transformation of a benign teratoma. CONCLUSIONS: This case shows the significance of large sampling, precise recording of the gross aspects, histopathological examination, immunohistochemical analysis, and the help of radiological and clinical results to correctly diagnose uncommon tumors.

Von Hippel-Lindau (VHL) disease, an autosomal dominant genetic disorder caused by a germline mutation, is associated with non-functional and slow-growing pancreatic neuroendocrine tumor (PNET) and kidney cancer. We describe the case of a 46 year-old man with a 35 mm mass in the pancreatic head causing stricture of the bile duct and main pancreatic duct, a 55 mm mass in the pancreatic tail causing obstruction of the splenic vein (SV), and multiple masses of > 36 mm on both kidneys. We performed a two-stage resection. First, a total pancreatectomy with superior mesenteric vein (SMV) resection and reconstruction and retroperitoneoscopic right partial nephrectomy (NP) for five lesions was performed, followed by retroperitoneoscopic left partial NP of the five lesions 6 months later. Postoperative histopathological examination revealed NET G2 in the pancreatic head with SMV invasion and somatostatin receptor type 2A (SSTR2A) positivity, NET G2 in the pancreatic tail showed SV invasion and negative SSTR2A, and multiple clear cell renal cell carcinomas (RCC) were also noted. Multiple liver recurrences occurred 22 months after primary surgery. The patient remains alive 41 months after primary surgery. Kidney cancer generally determines VHL prognosis; however, we experienced dual-advanced PNETs with a more defined prognosis than multiple RCC associated with VHL.

INTRODUCTION: We investigated the factors associated with synchronous multiple early gastric cancers and determined their localization. METHODS: We analyzed 8,191 patients who underwent endoscopic submucosal dissection for early gastric cancers at 33 hospitals in Japan from November 2013 to October 2016. Background factors were compared between single-lesion (n = 7,221) and synchronous multi-lesion cases (n = 970) using univariate and multivariate analyses. We extracted cases with two synchronous lesions (n = 832) and evaluated their localization. RESULTS: Significant independent risk factors for synchronous multiple early gastric cancer were older age (≥75 years old) (odds ratio [OR] = 1.257), male sex (OR = 1.385), severe mucosal atrophy (OR = 1.400), tumor localization in the middle (OR = 1.362) or lower region (OR = 1.404), and submucosal invasion (OR = 1.528 [SM1], 1.488 [SM2]). Depressed macroscopic type (OR = 0.679) and pure undifferentiated histology OR = 0.334) were more common in single early gastric cancers. When one lesion was in the upper region, the other was more frequently located in the lesser curvature of the middle region. When one lesion was in the middle region, the other was more frequently located in the middle region or the lesser curvature of the lower region. When one lesion was in the lower region, the other was more frequently located in the lesser curvature of the middle region or the lower region. CONCLUSION: Factors associated with synchronous multiple early gastric cancer included older age, male sex, severe mucosal atrophy, tumor localization in the middle or lower region, and tumor submucosal invasion. Our findings provide useful information regarding specific areas that should be examined carefully when one lesion is detected.

BACKGROUND: In Japan, the standard management of Barrett's esophageal adenocarcinoma after endoscopic submucosal dissection involves follow-up; however, multifocal synchronous/metachronous lesions are sometimes observed after endoscopic submucosal dissection. Risk stratification of multifocal cancer facilitates appropriate treatment, including eradication of Barrett's esophagus in high-risk cases; however, no effective risk stratification methods have been established. Thus, we identified the risk factors for multifocal cancer and explored risk-stratified treatment strategies for residual Barrett's esophagus. METHODS: We retrospectively reviewed the data of 97 consecutive patients with superficial Barrett's esophageal adenocarcinomas who underwent curative resection with endoscopic submucosal dissection. Multifocal cancer was defined by the presence of synchronous/metachronous lesions during follow-up. We used Cox regression analysis to identify the risk factors for multifocal cancer and subsequently analyzed differences in cumulative incidences. RESULTS: The cumulative incidences of multifocal cancer at 1, 3, and 5 years were 4.4%, 8.6%, and 10.7%, respectively. Significant risk factors for multifocal cancer were increased circumferential and maximal lengths of Barrett's esophagus. The cumulative incidences of multifocal cancer at 3 years were lower for patients with circumferential length < 4 cm and maximal length < 5 cm (2.9% and 1.2%, respectively) than for patients with circumferential length ≥ 4 cm and maximal length ≥ 5 cm (51.5% and 49.1%, respectively). CONCLUSIONS: Risk stratification of multifocal cancer using length of Barrett's esophagus was effective. Further multicenter prospective studies are needed to substantiate our findings.
